Whether it's fast --or-- slow --- that's NOT the point. The issue is options, compatibility, flexibility, available on competitors, etc.
If you're like me, and sync daily --- to get my calendar / address book updates, it should be quick as a bunny even at turtle-slow 'B" WiFi speeds!!
================================================== ===========
Update: REAL USB traffic analysis
Utility: USBlyzer (
USBlyzer - Software USB Protocol Analyzer for Windows)
Setup: Connect iPhone, start iTunes --- do a complete sync
USB transfer data:
--Start capture, sync again to get a baseline (nothing to sync):
9.156.640 bytes total, 3,536,187 in, 5,620,453 out, 32.5 sec
--Add one calendar entry and sync:
9,146,148 bytes total, 3,533,119 in, 5,613,029 out, 36.5 sec
--Add one contact entry and sync:
9,144,634 bytes total, 3,532,581 in, 5,612,053 out, 34.5 sec
WiFi real-world speeds:
Comparison_of_wireless_data_standards
802.11b (11 Mbits/sec max) typical 2 Mbits/sec (250KBytes/sec)
802.11g (54 Mbits/sec max) typical 10 Mbits/sec (1,25MBytes/sec)
802.11n (200 Mbits/sec max) typical 40 Mbits/sec (not on iPhone)
Time required to sync w/WiFi (non-backup ) at 100% utilization:
802.11b: -- 36.4 seconds (9.1 MByte/250 Kbyte)
802.11g: -- 7.3 seconds (9.1 MByte/1.25 MByte)
Note1: Obviously, iTunes does a lot of computer crunching and very little data transfer (ya think

)
Note1: My test setup sync also includes iTunes attempting to install 8 (FW3.0) apps on a 3G running FW2.2.1.
Note2: I did not test the daily/weekly/monthly full-sync scenario, as the amount of data transferred varies extremely from user to user. Obviously a lot more data is transferred, but not so much as to make WiFi unusable.
Conclusion:
Wireless iPhone/iTunes sync'ing is WELL within WiFi limitations.
USB --may-- only be necessary/recommended for major syncs (music, movie, app and photo?)
